Connections at SFO: the honest numbers
The indicative minimum international-to-international connection at San Francisco is 90 minutes on a single booking with bags checked through. On separate tickets, add roughly 90 minutes: you'll collect bags, recheck them, and re-clear security — and no airline is obliged to help if the first leg runs late.
Transfer specifics
- Same US rule: no airside transit — everyone clears immigration and customs, then re-clears security.
- Terminals connect airside for many (not all) gate pairs post-security, and the AirTrain loops landside — SFO transfers are gentler than JFK/LAX but still budget 90 min+.
Leaving SFO during a layover
Same rule as every US airport: NO airside transit — everyone clears immigration and customs even when connecting, so an ESTA or visa is required regardless. The upside: BART runs from inside the airport to downtown in ~30 minutes, making SFO one of the easiest US city-dash airports. The city is about 35 minutes away one-way; as a rule of thumb you want 6+ hours before exiting is worth the queues, and you should be back through security 90 minutes before boarding.
Worth your hours in San Francisco
- 6h+: BART from the International Terminal to Embarcadero (~30 min) — Ferry Building food, waterfront walk, back
- 8h+: add a Mission burrito or a cable-car photo stop
- Foggy-day fallback: the SFO Museum exhibitions airside are genuinely worth an hour
Staying airside instead
- Probably the best US airport for killing time: real museums (SFO Museum rotates genuine exhibitions), an aviation library, and a yoga room
- Strong local food — Napa wine bars and proper sourdough beat chain fare
- Free water refill stations everywhere and famously clean terminals
Sleeping, showers and lounges at SFO
Sleep: Freshen-up day rooms and nap pods vary by terminal; the Grand Hyatt connected by AirTrain rents day rates.
Showers: In some lounges and the Freshen-Up locations.
Lounges: Good Priority Pass coverage by US standards, concentrated in International Terminal G/A.
Overnight reality: Open 24h and safer than most US hubs, but seating is armrest-heavy; the connected Grand Hyatt is the comfortable answer.
SFO layover FAQ
Do I need an ESTA to connect through San Francisco?
Yes — the US has no airside transit at any airport. Everyone clears immigration and customs even when only connecting, then re-clears security.
Can I get into San Francisco city on a layover?
Easily by US standards — BART runs from inside the International Terminal to downtown in ~30 minutes. With 6+ hours you get the Ferry Building and waterfront comfortably.
Is 90 minutes enough to connect at SFO?
On one booking it's the working floor once immigration and re-screening are counted — SFO processes faster than JFK/LAX on average, but 2 hours is still the calm zone.
What's there to do inside SFO on a layover?
More than any US airport: rotating SFO Museum exhibitions, an aviation museum and library, a yoga room, and genuinely good Bay Area food airside.
